STAND-BOILER.

Application filed May 28, 1913.

To @ZZ whom it may concern Be it known that l, ROBERT T. PARISEN, acitizen of the United States, and resident of Knoxville, in the countyof Allegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Stand-Boilers, of which the following is aspecification.

rEhe primary object of this invention is to provide a stand boiler ofimproved construction having a water heating coil located in a shellwhich is positioned within but closed to the boiler, whereby arelatively large area of heat-radiating surface is eX- posed to thewater so that practically all of the heat is utilized.

A further purpose is to provide a burner and combined burner-inclosingchamber andl drip pan of novel construction, together with improvedmeans for securing the chamber as well as the boiler-supporting legs tothe vlower portion of the boiler.

In the accompanying' drawings, Figure 1 is a front elevation of theimproved boiler, and Fig. Q is a vertical longitudinal section of thesame. Figs. 3 and l are sectional plan views taken on lines 3dS and 4wd,respecf tively, of Fig. 1. Fig. 5 is a view of the burner-inclosingchamber detached from the boiler. Fig. 6 is a sectional plan of theburner chamber taken on line G-G of Fig. 2. Fig. 7 is a vertical sectionof the burner and burner chamber taken on line 7 7 of Fig. G.

Referring to the drawings, 2 designates a vertical shell of acylindrical stand boiler of which 8 is the crown and 4 the bottom. Thelower extremity of the shell is reinforced by the depending hoop-likerim 5, spot welded thereto at 5, and depending from the rim are legs 6,the upper extremities of thelcgs being flanged at 7 to fit the innerface of the rim to which each is secured by a screw or bolt 8.

Within and closed to boiler 2 and open through the bottom thereof iscylindrical shell 9, and extending from the top thereof through crown 3is vent pipe 10 which projects slightlv above the crown with oppositesides of the projecting portion slotted at 11. lt will be understoodthat shell 9 and pipe 10 are sealed to the boiler interior and beingsurrounded by the water being heated a large area of heat radiatingsurface is ex- Specifcation of Letters Patent.

posed to the water in addition to the water heating coil presently to bedescribed, thereby increasing the etliciency of the heating means.

Located within and depending` from shell 9 is water heating coil 12 withthe lower extremity thereof extended laterally at 13 and connected tobottom l by coupling 111. A drain 15 may be extended from coupling 141,as shown. The upper extremity of the coil is extended upwardly throughvent 10, as indicated at 16, and is bent laterally through one of slots11 and connected by coupling 17 with crown 3, and this coupling may beutilized as a connection for the hot water service pipe 18. Cold waterinlet may be connected to the crown at the opposite side vent 10, infact the crown openings may be used interchangeably for the hot and coldwater connections.

Flue pipe 10 has a slip joint connection with the slotted extremity ofvent pipe 10 but is held by pipe 16 from fully covering slots 11, andthe air admitted through the uncovered portions of the latter operatesto check the draft upwardly through pipe 10.

rlhe lower portion of the coil is inclosed bv the burner chamber 20having the open annular top portion 21 which connects with and forms adownward continuation of shells 9. Beneath rim 21 the chamber isenlarged at one side at 22 to provide a frame for door 23, the doorenlargement being curved complementary with rim Project ing upwardlyfrom the door enlargement are lugs 211 which engage the inner face ofrim 5 with screws or rivets 25 extending through the rim and lugs,thereby supporting the chamber 20 in position to form a. down wardcontinuation of shell 9. Annular part 21 of the burner chamber isslotted at 2G to embrace coil extension 13.

The ring-like gas burner 27 is adapted to be entered in the chamberthrough door 23 with the gas inlet tube 28 thereof extending throughopening Q9 in the bottom of chamber 20. The air inlet portion 8O of saidopening is in line with vertical air passage 31 through burner 27,thereby supplying air in ample amount vfor combustion, the supplybeingsupplemented by air admitted through openings in the wall of thechamber, also through openings 23 in the door.

Burner tube 2S is flanged on opposite sides at82 with the flangesentered in offsets 29 of opening 29, and the burner is secured by setScrew 33 in lug 33 projecting from the chamber bottom. A mixer tube Saisheld in place in gas inlet 28 by set screws carried by flanges 32, withgas supply pipe 36 extending to the mixer from gas regulating valve 37having its thermostatic extension 38 fitted in bo-iler 2 with the valvecontrolling the flow of gas to the burner. The thermostatic Valve may beof usual or any preferred construction.

Chamber 22, in addition to inclosing the burner, operates as a drip panto catch and retain the condensate from the coil until it evaporates,flange 40 around bottom openings 29 and 30 and ledge-like flange ll atthe door opening preventing the water from running out. Vith the chamberbeneath and in line with the coil the drippings are caught andk confinedin relatively close proximity to the burner and evaporate before therecan be any overflow. Flange l0 serves to support the burner, as shown.

lVater heating apparatus construction as herein shown and described issimple, durable and highly efficient. The parts thereof are easilyaccessible and may be readily assembled. The coil connections with theboiler are so arranged and located that they may be convenientlydisconnected for renewing or repairing the coil.
